furuno display units models 2400& 1600

Hello there,
I got 3 furuno display units models 2400& 1600 ,their yellow/green
CRT shows a freezed straight line when powered on 13V; having this
line turning 360 ° all the time is a simple matter of feeding the
proper signals to a stepper motor that controls the rotation of the
yoke around the neck of their CRT.
Can I do that without the antenna units & simple internal mods ?
If I could have them work the way I want, my daughter will have fun
with the scopes, as she wants to be a space controller; then she will
"see" the invaders coming ;- )
Thank you & happy new year to all.
Patrick
Not without suppling a Bearing Input signal to the Main Connector.
The Bearing Input is nothing more than a Pulse Train generated up
in the antenna, by an LED/PhotoDiode Pair with a ChopperWheel in
between. A simple replacment would be a NE555 running at 1800Hz
and fed into the Bearing Input connection.
